Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04L 7/00
H04L 25/00
H04L 25/40

US Classification:

375372, 375371, 375373, 375376, 375355, 713503, 370505, 370229

Abstract:

Methods and apparatuses for compensating for differences in communication system transmit and receive clock signal frequencies include buffer timing modification and sample addition. In buffer timing modification, a buffer clock signal is interrupted as needed to slow the rate of data through the buffer. In sample addition, pseudo samples are inserted into a data stream to compensate for timing differences.

Appl. No.:

12/431155

Inventors:

Robert W. Zopf - Rancho Santa Margarita CA, US
Vivek Kumar - San Jose CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

G10L 21/02
G10L 19/00

US Classification:

704228, 704501

Abstract:

A bit error concealment (BEC) system and method is described herein that detects and conceals the presence of click-like artifacts in an audio signal caused by bit errors introduced during transmission of the audio signal within an audio communications system. A particular embodiment of the present invention utilizes a low-complexity design that introduces no added delay and that is particularly well-suited for applications such as Bluetooth wireless audio devices which have low cost and low power dissipation requirements.

International Classification:

H03M 13/00

US Classification:

714774, 714 3, 714747

Abstract:

Systems and methods are described for managing bit errors present in an encoded bit stream representative of a portion of an audio signal, wherein the encoded bit stream is received via a channel in a wireless communications system. The channel may comprise, for example, a Synchronous Connection-Oriented (SCO) channel or an Extended SCO (eSCO) channel in a Bluetooth wireless communications system.

Inventors:

Jane Aldrich - Lawrence KS, US
Vivek Kumar - Dublin CA, US

International Classification:

C07C229/22

US Classification:

525/333300, 562/567000

Abstract:

A synthetic reaction to produce [2-(2-aminoethoxy)ethoxy] acetic acid (AEEA) derivatives. This synthetic reaction does not require isolation and purification of intermediates. The AEEA derivatives can be used to synthesize high load polystyrene-polyethylene glycol-like resins having excellent swelling characteristics.

Abstract:

A composition, and method for a targeted drug delivery is disclosed in treating central nervous system injury, including blast hearing loss, traumatic brain injury (TBI) and the like, by administering a subject with nanoparticle-based minocycline formulations. The formulation contains nanoparticles encapsulating minocycline for neuroprotective effect in TBI. Albumin nanoparticle-based minocycline formulations provide enhanced delivery to brain, and reduced toxicity at minimal dosage for treating a subject suffering from central nervous system injury including blast induced traumatic brain injury (bTBI). Nanoparticle administered at minimal dose in rat blast TBI model crossed blood-brain barrier (BBB) and enhanced therapeutic concentration compared to free minocycline. Provided is an effective and safe minocycline delivery in TBI with minimal or no toxicity for neuroprotective therapy. Studies indicate performance for behavioral (acute and chronic), pathological (chronic) and hearing loss mitigation using the disclosed drug and nanoparticles in rat moderate bTBI model.
